Aachener Bachverein is the oratorio choir of Evangelische Kirchengemeinde Aachen (protestant church). The choir consists of about 120 active members of all denominations and is considered as one of the most steeped-in-tradition art organisations of this region. Continuity and quality mark its contribution as „body of sound to Aachen’s music life“. Aachener Bachverein performs regularly the works of J. S. Bach and beyond that feels also obliged to the choral repertoire from the early Baroque to the present. As choir of Evangelische Kirchengemeinde, Aachener Bachverein performs church music in the Annakirche. In 2013 the choir celebrates its 100th anniversary.
The Kammerchor Aachener Bachverein performs fastidious works of all epochs after short intensive rehearsals. In addition, concert tours and broadcast recordings are taken regularly.
